INDEX.

SPECIFICATION forming part of Letters Patent No. 330,285, dated November l0, 1885.

Application tiled December 16, 1884. Serial No. 150,535.

` siding at Englewood, in the county of Cook and State of Illinois, and a citizen ofthe United States, have invented a new and useful Im'- provementin Indexes, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a plan showing a book with one leaf of the cover and the attached index open; Fig. 2, an edge View of the book and index lifted away from the book. Fig. 3 is an edge View showing the book and index in another position.

Indexes for letter-books, ledgers, and other blank books are used in two ways: first,when making entries in the indexes, and, second, for purposes of reference.

' It has been found desirable to so connect an index with the book with which it is to be used that the index can be spread open outside of the book Ior use, and be returned into the book when not in use, so that the proper index will always be found with the proper book.

To such end my invention consists in the combination, with a book, of an index having letters along its edge, and provided with a flexible folding extension, said extension being secured at one end to the cover at a point within its edges, to bring the index letter along the front edge of the cover when the book is closed and retain the greater portion of said extension inside the limits of the bookcover when the index is outside of the book, as hereinafter more fully described.

In the drawings, A represents a blank book, one cover of which, B, is open. C is the index for the book A, provided with a paper or by a piece of cloth at the point d and also at e, because at these two points the part D is to be folded.

(No model.)

f are the index-letters upon leaves of the index. When the index is opened outside of the book, the parts will be in the position rep-- resented in Fig. l. When the index is folded into the book, the index-letters must necessarily be in sight.

In Fig. 2 I have shown the index lifted away from the cover B of the book preparatory to being brought into the position shown in Fig. l, and in Fig. 3 I have shown the parts in the position 'which they will occupy just before the index is laid upon the table or desk.

Vhen entries are to be made in the index, it is to be laid open, as shown in Fig. 1,when the index will be wholly outside of the book A. The index can be folded over within the covers of the book, as before stated, the part D being in effect hinged upon the inside of the cover B along the line g.

It will be observed that when the index is folded into the book the index-letters will be exposed to view, being on the outer edge of the book, and it is impossible to fold this index in the book in such manner that the index-letters will not be exposed to view/,which is an important feature. For many purposes also it is very much more convenient to have the index either at the top or bottom of the book with which it is to be used than at one side.

the book. To attach the index at the front of the book instead of the back, it is necessary to extend that part of the index-cover which in Fig. lis upon the left-hand side. To attach the index so that it will,when open, be at the top of the book instead of at the bottom, the extension D on the cover must be at the bottom of the index instead of at the top.

I do not claim, broadly, an index combined with a book so that the former can be opened and spread out by the Side of the book and folded therein.

I have described the part D as an extension on one side of the cover of the index. Of

course, this part D may be made separate from the cover of the index and be suitably connected therewith.
